Specification of Letters Patent.

Patented Jan. 19, recs.

Application filed October 17, 1%7. Serial No. a t;

To all whom it may concern I Be it known that I, GEoRenL. PATTERK SON, a citizen of the United States, residing at New York, county of New York, State of New York, have invented certain new and when a house is built, so that the bell proper 1y and operating mechanism may be quic installed therein at a later time.

Figure 1 is a plan view of a bell and certain of the associated parts;,Fig. 2 is a side elevation, partly in section; Fig. 3 is a sectional view, partly broken away; Fig. 4 is a front elevation of the receptacle.

1 represents the receptacle which is hollowed out to receive the socket 2, which in this particular instance includes two terminals 3 and 4 (Fig. 4).

5 is a conduit through which the wires of the circuit pass (see Figs. 2 and 3). In ordinary building construction it is customary to provide conduits for the sale-guarding and protection of circuit wires. In this instance the part 5 represents one end of such a conduit, and this leads into and makes connec tion with the receptacle 1. This receptacle .1, in ordinary building construction, would be placed substantially flush with the wall in which the bell is to be located.

The apparatus is provided with the usual gong 6, mounted on the extension 7 of the irame support 8; also the usual hammer 9 operated by electro magnets 10 in the ordinary manner. This frame 8, as shown, is substantially flat and carries the binding posts Hand 12.

13-14 are the wires which res ectively lead from the binding posts 11 an 12 to a plug 15, having two terminals adapted to be inserted in the socket 2. Within. the receptacle 1 is sufficient space to receive the slack pi ivires 1314, when the parts are assemconnected to the 16 isa cover for the electro magnets and associated parts, which is secured to the frame'S.

17-18 arev bosses within the receptacle 1, bymeans of which the frame 8'n1ay be secured thereto by the usual screws, as indicated at 19--19 (Fig. 1).

When the frame 8 is secured to the receptacle 1, there remains nothing to do but to attach the cover 16. This may be easily effected by means of screws passed through the screw-passages 20 (Fig. 1) in the frame 8.

From the foregoing it will be seen that the receptacle 1 is of a suitable construction to provide a well protected, solid foundation. The lug 15 is connected with. socket 2. The bell frame 8 is then secured to receptacle 1 by the aforesaid screws'and, if desired, by

Finally means of an additional screw 21. the cover 16 is applied. Between the cover 16 and the frame 8, and between the frame 8 and the receptacle 1,packing gaskets are introduced.

The proper osition of the bell is indicated in the severe figures and, as will be seen when theparts are assembled, it is practically impossible for dust, or water to enter the receptacle or cover from the outside. In the event condensation should take place in conduit 5, any slight amount of dampness that mi ht enter from this source could readily esc ape through the outlets 22.

It is unnecessary to describe the'particu lar construction of. the circuits, or the mechanism by which the hammer is connected, since that may be modified invarious ways.

As will be observed, the'conrrections for the binding osts 11 and 12 are made at the back, instead of at the edge of the frame 8, as will beseen in Big. 3. Thus, by this construction, not only is the bello crating mechanism thoroughly protected, terminals are likewise safe-guarded.
